Why would another fund be necessary when anyone can already donate to the existing fund. I shall happily donate if necessary - as I have no problem at all with how the McCanns would choose to use my donation.
Faith - do you think a separate Justgiving fund would be allowed to operate without the attention of those sceptics who would pay just for the gleeful pleasure of posting their poison? I don't.
You may not have any problem with how the couple choose to use your donation to the fund Benice but there are many that do and it is those individuals who would be reassured that their donation was going to the actual search rather than the McCann's legal bills if another mechanism was set up to specifically pay for those legal bills.
As to your second paragraph the possibility that the spectics would use a Justgiving page to 'post their poison' didn't stop both Kate and Gerry setting up just such a page to raise money for MP so why should it be a deterrent to the supporters now ?
